LEVOIT Core 300-P Review: Does a Pet Air Purifier Actually Help?

The LEVOIT Core 300-P made a noticeable difference in air quality with three dogs in the house. Pet odor reduced, dust on surfaces decreased, and my allergic friend can now visit without issues. It's not magic, but for ~$100, it's one of the better investments I've made for living with pets.
Skip to our picksThree dogs in a 1,500 square foot house. You can imagine how the air quality was. The "pet smell" was constant. My friend with allergies couldn't visit. I tried candles, sprays, opening windows—nothing really worked.
I was skeptical about air purifiers. They seemed like an expensive placebo. But the LEVOIT Core 300-P kept coming up in pet owner forums, so I tried it.
Four months later, I'm a convert. Here's what actually changed.

I put this in my living room—the main dog hangout area. Ran it continuously on auto mode. Here's what happened:
The Pet Odor
This was my main concern. After about a week of continuous use, I noticed the room smelled... cleaner? Not air freshener clean—just the absence of that lingering pet smell.
The real test: my allergic friend visited and didn't have a reaction for the first time. That alone was worth the purchase price.
Dust and Dander
I clean less now. Noticeably less dust on surfaces. The pre-filter catches a lot of dog hair—I can see it when I check the filter. That's hair that used to float around.
Noise Level
On low/sleep mode, I genuinely forget it's running. On high (which I rarely use), it's noticeable but not annoying. Not a white noise machine, but not intrusive either.
Who Should Buy This?
- Pet owners dealing with odors and dander
- Anyone with pet allergies (yourself or visitors)
- People in smaller spaces with pets

🏆Also Worth Checking: LEVOIT Core 300 Replacement Filter (Pet Allergy)
Replacement filter — genuine LEVOIT pet allergy filter for Core 300 series. Replace every 6-8 months.
- Those who want cleaner air without constant cleaning
It won't replace regular cleaning. But it handles the airborne stuff that cleaning can't fix.
The Honest Pros and Cons
Pros
- Actually reduces pet odor (not just masking)
- Quiet enough to run continuously
- Pet-specific filter design
- Reasonable price point (~$100)
- Easy to use—just plug in and run
Cons
- Only covers 219 sq ft (need multiple for big homes)
- Replacement filters cost $25-30
- Filter needs replacing every 6-8 months with pets
- Won't eliminate all odor (helps significantly, not 100%)
Tips for Best Results
- Run it continuously—turning it on/off reduces effectiveness
- Place it in the main pet area
- Check the pre-filter monthly and vacuum it
- Replace the main filter on schedule (don't stretch it)
- Consider one per main room if you have multiple
Pro tip: The auto mode is actually useful. It ramps up when it detects particles and quiets down when the air is clean.
The Bottom Line
I went from skeptic to advocate. The LEVOIT Core 300-P won't solve every pet-related air quality issue, but it makes a real, noticeable difference. The pet odor reduction alone was worth the purchase.
My verdict: Best value air purifier for pet owners. At ~$100, it's not a huge investment, and the results are tangible. If you're living with that "pet smell" and nothing else works, this actually does.
Just budget for replacement filters—they're not cheap, but they're necessary for the thing to work.
